DEVICE FOR SETTING RUBY-PINS IN WATCHES.

SPECIFICATION forming part of Letters Patent ll'o. 371,019, datedOctober 4, 1887.

Application filed May 11, 1887.

To all whom it may concern.-

Be it known that I, DITON H. ABNEY, a citizen of the United States,andaresident of Pilot Grove, in the county of Cooper and State of Missouri,have invented certain new and useful Improvements in Devices for SettingJ ewel- Pins in Watch-Balances; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification, and in which Figure 1 is aperspective view of my improved device for setting jewel-pins in theroller-tables of balance -.wheels for watches. Fig. 2 is a front View ofthe same. Fig. 3 isa longitudinal vertical sectional view of the devlce,showing the balance-wheel in position and thejewel held in the jaws ofthe device; and Fig. 4. is a top view of the casing for holding thebalance-wheel.

Similar numerals of reference indicate corresponding parts in all thefigures.

My invention has relation to devices for setting jewel-pins in theroller-tables of balancewheels of watches; 'and it consists in theimproved construction and combination of parts of such a device, ashereinafter more fully described and claimed.

In the accompanying drawings, the numeral 1 indicates a foot-plate, towhich the base 2 of the frame is secured, the frame consisting, besides,of the base of a handle, 3, projecting rearward and a forwardly andslightly downwardly curved arm, 4. The base is provided wlth alongitudinally and vertically slotted arm, 5, projecting forward, and acylindrical casing or barrel, 6, is provided with a bolt, 7, sliding inthe slot 8 of the said arm, the said bolt projecting from the bottom ofthe barrel and having a thumb-nut, 9, upon it, which bears against theunder side of the slotted arm and serves to adjust the barrel. Thebarrel is diametrically divided and has the two halves hinged togetherby a hinge, 10, and locked together at the free edge by a spring, 11,pro jecting over the said edge and bearing against the side of the otherhalf, and the divided top of the barrel is provided with a central aper-Serlal No. 237,861.

ture, 12, and with a small recess or depression, 13, at one side of thesame.

The upper arm of the frame is formed with a vertical perforation, 14, inwhich an" arm, 15, projecting rearwardly and downwardly from the back ofa plunger, 16, slides, being held adjusted in the perforation by meansof a set-screw, 17, passing through one side of the perforation andbearing against the arm, and the lower end of this plunger is cut awayat the rear side to make aspace above the central perforation of thebarrel, as shown at 18, and has a truly vertical groove or notch, 19, inthe forward side of its lower end,into which notch or groove thejewel-pin may be placed.

A lever, 20, is fulcrumed at its middle upon a stud, 21, projectingforward from the plunger, and the lower inwardly-bent end of this leverbears with its fiat face 22 against the face of the lower end of theplunger, covering the groove or notch in the same, while its upper endhas a flat spring secured to it with its upper end and bearing againstthe plunger with its lower rearwardly-inclined end, the said end of thespring 23sliding upon the face of the plunger and serving to force thelower end of the lever to bear against the lower end of the plunger.

A bracket, 24, is secured at the inner end of its inwardly-bent arm 25upon the end of the longitudinally-slotted arm of the frame upon a boltor screw, 26, inserted through the perforated end of the arm and intothe end of the slotted arm, and the upper end of this bracket is formedwith an obliquely-perforated eye, 27, into which a funnel-shaped tube,28, may be secured, the said tube contracting to a very small apertureor nozzle, which may be brought to point immediately over the recess inthe top of the cylindrical casing.

When the device now is to be used, the balance-wheel is first removedfrom the watch, and after removing the remnants of the former jewel-pin,if one pin has been formerly inserted and broken off, the wheel isplaced within the barrel, the hair-spring remaining upon the staff orarbor of the wheel, and the rollertable 29 resting above the aperture inthe top of the barrel, thepivot of the staff projecting upward. Thejewel-pin 30 is now ICC placed in the groove or notch of the plunger, 3

which has been removed by loosening the setscrew, the flat end ofthelever bearing against the flat side of the pin and clamping the sameand the end of the pin projecting slightly below the end of the plunger.The plunger is now inserted in the frame and brought down against theroller-table, which is adjusted by moving and adjusting the barrel so asto bring the perforation for the pin to register with the end of thesame, whereupon the plunger is secured by the set-screw, the end of thepin fitting in the perforation. A small quantity of shellac is nowplaced in the recess or depression, which is immediately undertheperforation for the pin, and the device is inverted, the shellacbeing placed directly over the perforation if the pin does not penetratethe perforation entirely, while it is placed slightly to oneside of thesameif thepin projects through the perforation. The funnel-shaped tubeor nozzle is now adjusted by means of its bracket turning upon thescrew, so as to bring the wide outer end within reach of a blow-pipe andthe narrow end immediately above the shellac, whereupon the flame of asuitable burner is blown by the blow-pipe through the nozzle, heatingand melting the shellac, and after the shellac again has cooled andhardened the pin is secured and the wheel is ready to be again insertedin the watch.

It will be seen that the spring is protected from the heat applied tothe shellac by the top of the barrel, and the pivot or point of thestaff is protected by the cutout lower end of the plunger, so that onlythe shellac will be exposed to the heat, and the nozzle will guide theflame from the burner and blow-pipe directly upon the shellac, andlikewise prevent the heat from affecting the spring or any other part ofthe balance, although this nozzle may be dispensed with and theprotection afforded by the barrel be deemed sufficient, the nozzle,however, adding to the effectiveness and safety for use of theapparatus.

The groove or notch in the plunger being vertical, it will be impossibleto place the pin into the perforation in the roller table in any otherposition to the same but at right angles to its surface, parallel to thepivot and staff.

By having the barrel adjustable the device may be used for wheels ofdifferent sizes having different distances between the staff and theperforation in the roller-table for the pin, and the pin will always besecured in the perforation in the right position, as the flat face ofthe pin will bear against the lower end of the lever, consequentlyfacing outward.

Having thus described my invention, Iclaim and desire to secure byLetters Patent of the United States-'- 1.
